GIB/DER OR BEAM.

Specification 'of Letters Patent.

Patented July' 3o, 19er..

Application filed December 6` 1906. Serial No. 346,614,

To all whom 'it may concern: f

I le it known that I, PIERRE ZUeco, a resident of the oily of New York, county of New York, and State-of New York, have invented certain new and'. useful Im? provi-ments in Girders or Beams, of which the following is aspocilcation.

This invention relates to theconstruction of concrete or muni-nt. girdors or beams, and more particularly to the manner of arnioring same. i'

Tho object of this invention is to provide an armor l'or concreto or lcement construction of the class above described. and to form the same in such a manner that il muy be easily and quickly prepared for different structures. i

A further object of the invention is to provide a steel Inu' having a bar integral therewith and an integral web, each adapted to be sheared and bent atfangles lbon-l rom' so as to form a more durable reinforcement.

' 'lo this ond l make use of a bar, the particular'con- ;1|'\| -l ion ol which and the manner of shearing its various pui-fs, will he more fully described and specifici ally poi ntcd out in the appended claims.

In the drawings forming a part of'this specification:

'Figure l, is a side elevation of a beam showing my impro vcd bar as applied, the beam being in s action; Fig. 2,

` a pinspcctive View of a bar constructed in accordance with my invention; Fig. 3, is a cross sectional view of |hrbar; and Fig. 4, illustrates the manner of tying the shi-nml har to the barl proper. l

Referring by numerals to the drawings, l represents a har having a web 2, and an integral bar 3, connected by n w'ob Il, the bar 3, being substantially at right angles' lo the web 2. By shearing the web 4 from the res] wcti vo ondsol the bars towards the center, the ends of 1ln har 3, may he bent up at an angle from tho bar land parallel thereto us shown in Fig. 2, so as to obtain the ol'l'r-i-t of a continuons beam. The web 2, is sheared in sci-lions 5, and said sections are bent up at righiv angli-s to the har as clearly shown. Any desired number nl' ilwso slwarcd-sections may be employed the nlnnlwr yur-ying according to the strength it is desired 1o oblniihI It is also to be understood that l may use.

two ofItlh-se bars and tio the same together. The bar by the strips above described.

In some cases it may not be necessaryto employ the 3, is tied to the bar 1, by means of a strip 6, which is bent around the respective bars and provided upon its respective ends with a clamp 7, such strips n'iay be employed WhcntWo of the bars are used in place of one.

However, if additional strength is required a bar 8 1r ay be placed parallel to the bar 1, and connected therewith tie strips 6, and in the absence thereof the free ends of the sections 5, may be bent over the bar 3, as shown at 9. Y

fI-Iaving thus described the various features of my invention, what I claim as newfand desire to secure by Letters Patent, is: y i

1. In an armored beain `or girder, two parallel bars connected tangentially by a web, one of the hars boingl larger thanthe other, a second web upon the larger bnr projecting tangentially therefrom and arranged at right angles to lhe first mentioned web, substantially as specified.

2. In an armored beam or girder, two parallel bnl-s con nectcd by a web. the web being cut so as to form-bifurcated ends, .the respective ends of one bar being bent at an :ingle from the other bar, a web upon the straight bar, said web beineP shear-ed in sections, the said shear-ed sections being bent at right angles to the bar, substantially as specified. l

3. In an armored-beam o1' girder, two parallel bars connected by a web, one ofthe bars being larger than` the other, a web upon the larger bar at right angles to the web connecting the bars, the web connecting the bars be iner sheared so as to form bifurcated ends, the respective ends ot' the smaller bars being bent :it an angle trom the larger bar, the web upon the larger bar being shear'ed in sections, said sections being bent at right angles to the bar, and -the strap for tying the upper bnr and the lower bar together, substantially as specified.

4. In an armored beam or girder, two parallel bars connected b v a web being cut so as to form bifurcated ends. the respective ends of one of the bar'sbeing bent up to obtain the effect of a continuous beam, a web upon the other bnr, said web boing sheared in sections, said sliea red sections being' bent at right angles to the bar and clamped over the bent bar, substantially as specied.
